PLEASE HURRY!! (b. s. answers will be reported) correct answer will get brainliest. Cylinder A contains 11.0 grams of CO2(g) and cylinder B contains N2(g).
The volumes, pressures, and temperatures of the two gases are indicated under each cylinder.
What is the total number of moles of CO2(g) in cylinder A?

Va=24.6 L Vb=24.6 L
Pa=1.0 atm Pb=1.0 atm
Ta=300. K Tb=300. K

Select one:
a. 4.00 mol.
b. Not enough information given
c. 0.250 mol.
d. 0.110 mol.
e. 0.500 mol.

c. electrical charges of ionic bonds.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
